GAUGE COCK.-

Application filed November 18, 1924. Serial No. 750,612.

To all whom it may concern.'

Be it known that I, MILLARD F. WATERS, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and" useful Improvements in Gauge Cocks; and 'I do hereby-declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relatesto new and useful improvements in water gauge cocks for testing the water level in boilers and the like, and is an improvement on my pending application Serial No.` 729,134 filed July 30, 1924.

The object of my present invention is to provide a gauge cock which is so constructed that the port sealing means will not be'v affected by heat, or corrosion. Another object is to arrange the parts of my device in such a manner that the ort will seat on the' valve sealing meansat rlght angles, ,thus effecting a perfect seal.

With the above and other objects in view which will appear as the description proceeds, my invention consists in the novel features herein set forth, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

Referring to the drawings, in which numerals of like character designate similary parts throughout the several views,

Fig. 1 is a view of my improved gauge,

partly in section, showing the sealing disk and the position of the discharge port with f relation thereto.

Fig. 2 is a view taken on line 2-2 of Fig.

"J1, and

Fig. 3 is a detail view of the screw threaded tip for engaging the sealing disk'.

' body in a smaller threaded aperture 'I as.

In the drawings, 1 represents the body` portion of my improved gauge cock, and is preferably composed of brass, threaded at one end 2 to enable it to be screwed into a boiler head (not shown). On 'the upper side of the body 1, I provide an upwardly, extending lug 3, integral therewith and having an aperture 4 therein. 5 .designates ,a longitudinally extending passage in the body 1, which terminates at the end 6 of the shown in dotted lines, Fig. 1, to receive the threaded neck 8 of a tip 9, alsoprovided As in my pending application, I provide a longitudinally extending rod 14, rotatable in the handle 10, terminating. at, its inner end in an enlarged squared portion 15, having a shoulder or head 16 integral therewith. The other end of the rod 14 is -squared as at 17 to receive a wrench or the like, and threaded -at 18, just belowsaid squared end 17, to receive a lock'nut 19.

On the squared portion 15 is a removable circular disk 2O provided with a squared aperture 21 which corresponds in shape with the squaredV portion 15 and is adapted to be revolved thereby. This disk is preferably composed of a substantially soft -rnetal and is beveled inwardly from its peproducing a perfect seal of the ports v5, 5a.

The operation of my device is similarI to that shown in my pending fpplicationl before referred to. vThe threaded portion 2 of the body is sc rewedv into a boiler head, the lug 3 extend-ing upwardly and supporting the handle 10 on ,its pivot. The weight of the handle forces the sealing disk 20 against the hard tip 9, causing the same to be seated therein and sealing the port 5a of the exhaust outlet.

.1 'By raising the handle 10, the seal is broken and steam or water allowed to exhaust. After o'ne portion of the beveled/face ofI the disk 2O becomes worn, the disk is f turned to'a new place, by loosening the lock nut 19 and applying a wrench to the end 17. `The disk may also be turned over on a new 'face by simply removing the lock nut 19 and pulling out the rod 14.

It is obvious that with my improved device, a perfect seal may be obtained, -due to the tip 9 of hard material engaging the disk l2t) of softer substance at right angles.

-as disclosed -in the appended claims.

What I claim and desire to secure by Letters Patent is 1. A gauge cock adapted to be securedv to a boiler head including an apertured body portion, a handle pivoted to said body portion, a sealing disk on said handle beveled inwardly from its peripheryon its port engaging face, the mouth of the aperture 'in saidbody portion being adapted to engage the beveled portion of said disk ait right angles thereto.

2. A gauge cock adapted to he secured to a boiler head, includin anapertured body portion having a tip of arder material than said body, a handle pivoted to said body portion, a sealing disk on said handle beveled-inwardly from its periphery on irts portengaging ace, said -tip being adapted to engage the beveled portion of said disk at right angles thereto.

3. A gauge cock as claimed in claim 2, Whereinsaid tip is composed of Monel metal. 4, A gauge cock as claimed in claim 2 wherein said. disk is beveled'on both faces. In testimony whereof I aix my signature.

Y MILLARD F. WATERS.
